`LimaVzDriver.Stop()` returned an error without stopping the VM when `CanRequestStop()` reported false, and it never removed the driver PID file. When launchd sends SIGTERM to the host agent of a LaunchDaemon instance, the host agent exits with `vz: CanRequestStop is not supported` and leaves `vz.pid` behind. Within the same boot this is harmless, because `ReadPIDFile` removes the PID file of a dead process, but after a reboot the recorded PID may have been reused by an unrelated process. The instance then shows up as `Broken` with "vz driver is running but host agent is not", and launchd with `KeepAlive` crash-loops `limactl start`. Ask the guest to shut down over SSH whenever the request could not be made through the Virtualization framework, not only for the macOS guests that ignore `RequestStop()`. The VM is never stopped forcibly with `VirtualMachine.Stop()`: that does not give the guest a chance to stop cleanly, and may corrupt the disk. Always remove the PID file when the driver stops, as the qemu and krunkit drivers already do. Related to #5087 Signed-off-by: Eugene Kalinin <e.v.kalinin@gmail.com>

Lima: Linux Machines
Lima launches Linux virtual machines with automatic file sharing and port forwarding (similar to WSL2).
The original goal of Lima was to promote containerd including nerdctl (contaiNERD ctl) to Mac users, but Lima can be used for non-container applications as well.
Lima also supports other container engines (Docker, Podman, Kubernetes, etc.) and non-macOS hosts (Linux, NetBSD, etc.).
Getting started
Set up (Homebrew):
brew install lima
limactl start
To run Linux commands:
lima uname -a
To run containers with containerd:
lima nerdctl run --rm hello-world
To run containers with Docker:
limactl start template:docker
export DOCKER_HOST=$(limactl list docker --format 'unix://{{.Dir}}/sock/docker.sock')
docker run --rm hello-world
To run containers with Kubernetes:
limactl start template:k8s
export KUBECONFIG=$(limactl list k8s --format 'unix://{{.Dir}}/copied-from-guest/kubeconfig.yaml')
kubectl apply -f ...
